Abstract

The invention relates to the field of suspension devices of vehicles, in particular to a pure-electric distributed multi-wheel mobile platform of intelligent control hydraulic suspension devices. A controller and a speed sensor monitoring the traveling speed of a mobile platform chassis in real time are arranged at the top of the mobile platform chassis, each axle support is provided with a distance sensor and an image sensor, and each electric wheel is provided with a rotation speed sensor for monitoring the rotation speed of the electric wheel in real time. Four completely symmetrically arranged son hydraulic cylinders are arranged outside each electric wheel main hydraulic cylinder, every five hydraulic cylinders are used in cooperation, the hydraulic suspension devices can be elongatedand shortened and incline, each hydraulic suspension device composed of five hydraulic mechanisms can achieve buffering and shock absorption effects on each whole electric wheel and even the whole mobile platform, and the problem that transverse force is generated in the working process of each main hydraulic cylinder, and thus the periphery on each main hydraulic rod slightly shakes is effectively solved.

Description

technical field [0001] The invention relates to the field of vehicle suspension devices, in particular to a pure electric distributed multi-wheel mobile platform with intelligent control hydraulic suspension devices. Background technique [0002] With the rapid development of new technologies such as battery energy storage technology, in-wheel motor technology, and new energy power generation, electric vehicles that are powered by batteries and drive wheels with electric motors are booming. Vehicle electrification is an important development trend in the future. The obvious advantages of electrification are higher or even extreme efficiency, power transmission without a large number of mechanical transmission structures, quietness and easy intelligent control. Now there are some electric vehicles on the market. Such electric vehicles generally have electric motors that drive the wheels to rotate through mechanical transmission devices, and some electric wheels are directly d...
